One-Pot Synthesis of α,ω-Chain End Functional, Stereoregular, Star-Shaped Poly(lactide)

摘要: The synthesis of stereoregular α,ω-chain end functional linear, telechelic, and star-shaped polymers copolymers is reported using a one-pot chain functionalization methodology. Aluminum methyl complexes are applied in combination with multifunctional initiating species to synthesize poly(lactide)s by the stereospecific ring-opening polymerization rac-lactide. quenching reactions an excess acid chloride molecules has enabled situ quantitative modification ω-chain ends such that primary secondary alkyl aryl groups can be incorporated.
